T-Mobile and Starlink to team up

9:10 pm

SpaceX and T-Mobile today announced that sometime next year T-Mobile cell phones will use the Starlink satellite constellation to fill in any dead zones in its cell coverage.

T-Mobile says it’s getting rid of mobile dead zones thanks to a new partnership with SpaceX’s Starlink satellite internet, at an event hosted by T-Mobile CEO Mike Sievert and Elon Musk. With their “Coverage Above and Beyond” setup, mobile phones could connect to satellites and use a slice of a connection providing around 2 to 4 Megabits per second connection (total) across a given coverage area.

That connection should be enough to let you text, send MMS messages, and even use “select messaging apps” whenever you have a clear view of the sky, even if there’s no traditional service available. According to a press release from T-Mobile, the “satellite-to-cellular service” will be available “everywhere in the continental US, Hawaii, parts of Alaska, Puerto Rico and territorial waters.” The service is scheduled to launch in beta by the end of next year in “select areas,” and Sievert says he hopes it will someday include data.

The system will require Starlink’s second generation satellites, which right now also require SpaceX’s big Starship for launch. Once operational however it will work on the cell phones customers already own.

Chuck Yeager – Breaking the Sound Barrier

6:01 pm

An evening pause: From a 1950s Air Force documentary, describing Yeager’s flight on October 14, 1947. The 75th anniversary of this achievement is thus only two months away. From the YouTube webpage:

Two nights before the scheduled date for the flight, Yeager broke two ribs when he fell from a horse. He was worried that the injury would remove him from the mission and reported that he went to a civilian doctor in nearby Rosamond, who taped his ribs. Yeager told only his wife, as well as friend and fellow project pilot Jack Ridley, about the accident. On the day of the flight, Yeager was in such pain that he could not seal the X-1’s hatch by himself. Ridley rigged up a device, using the end of a broom handle as an extra lever, to allow Yeager to seal the hatch.

Hat tip Mike Nelson.

Eroding glacial ice on Mars, dipping in the wrong direction

1:00 pm

Dipping wrongway ice terraces
Click for full image.

Today’s cool image is a variation of a similar phenomenon shown in a cool image I posted in July, dipping terraced layers stepping downhill toward a cliff face, rather than away from the cliff as you would expect. That previous example was located in chaos region in the northern mid-latitudes that I dub glacier country.

This example is instead found a completely different region of Mars, halfway across the planet. The photo to the right, cropped, reduced, and annotated to post here, was taken on March 1, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The arrows indicate the downward trend of those dipping layers, toward the cliff face.

The overview map below provides the context.

Pushback? BLM murderer of retired black St. Louis police captain found guilty

12:09 pm

David Dorn: Some justice at last
David Dorn: Some justice at last

Two years after the BLM riots of 2020, the murderer of retired St. Louis police captain David Dorn has been found guilty.

A jury has convicted Stephan Cannon in the death of retired St. Louis police captain David Dorn in June 2020.

Cannon was found guilty Wednesday on charges of first-degree murder, first-degree robbery, first-degree burglary, and three counts of armed criminal action. He is scheduled to be sentenced in the case on the morning of September 13.

Dorn had been killed by Cannon because Dorn had responded to a burglary alarm during those BLM riots and was trying to prevent the looting of a friend’s pawn shop. He was the ultimate blacklisted American, murdered because he stood for law, justice, and civilized behavior.

Dorn’s widow, Ann Dorn, also a retired St. Louis police officer, made it very clear in an op-ed shortly thereafter who she really blames for her husband’s death.

How SLS reveals the difference between state-run propaganda and real journalism

10:10 am

The cost of SLS

On August 29, 2022, NASA will attempt the first launch of a government-built, government-owned, and government-designed rocket in more than a decade. The rocket’s development took more than eighteen years, moved in fits and starts due to political interference and mandates, cost more than $50 billion, and has been both behind schedule and overbudget almost from day one. Along the way NASA management screwed up the construction of one multi-million dollar test stand, built another it will never use, mismanaged that test program, dropped a rocket oxygen tank, and found structural cracks in an early Orion capsule.

This dubious achievement, even if the launch and month-plus-long mission of the Orion capsule to lunar orbit and back is a complete success, is hardly something to tout. NASA claims it and this rocket will make it possible for America to explore the solar system, but any honest appraisal of SLS’s cost and cumbersome design immediately reveals that claim to be absurd. SLS can launch at best once per year, and in truth will likely lift off at a much slower rate. It will also eat up resources in the American aerospace industry from technology better designed, more efficient, and more capable of doing the job.

Worse, the generally sloppy management of this program, with numerous major errors in design and construction, raises serious questions about the safety of any future manned flight.

And yet, as this launch day approaches, the American established press is going ga-ga over SLS. Below are just a small sampling:

Webb detects carbon dioxide in atmosphere of exoplanet

8:42 am

Scientists using the James Webb Space Telescope have detected carbon dioxide in the atmosphere of a hot gas giant exoplanet about 700 light years away.

WASP-39 b is a hot gas-giant with a mass roughly one-quarter that of Jupiter (about the same as Saturn) and a diameter 1.3 times greater than Jupiter. Its extreme puffiness is partly related to its high temperature (about 900° Celsius or 1170 Kelvin). Unlike the cooler, more compact gas giants in our solar system, WASP-39 b orbits very close to its star – only about one-eighth the distance between the Sun and Mercury – completing one circuit in just over four Earth-days. The planet’s discovery, reported in 2011, was made based on ground-based detections of the subtle, periodic dimming of light from its host star as the planet transits or passes in front of the star.

Previous observations from other telescopes, including the Hubble and Spitzer space telescopes, revealed the presence of water vapour, sodium, and potassium in the planet’s atmosphere. Webb’s unmatched infrared sensitivity has now confirmed the presence of carbon dioxide on this planet as well.

This is only the beginning. Astronomers have told me repeatedly that the most important area of research in astronomy in the next few decades will be the study of known exoplanets and their make-up. Webb is now a new tool in that effort. Combined with other telescopes looking at other wavelengths scientists will be able to identify a whole range of molecules in the atmospheres of these transiting exoplanets. We will begin to get our first glimpse into what other solar systems are like.

Fred Astaire & Ginger Rogers – Never Gonna Dance

6:01 pm

An evening pause: We’ve had a lot of 1970s pop songs and dance recently. Here’s an example of one of the greatest movie dance numbers, from the 1936 movie Swing Time. Note how smooth and ballet-like it is, unlike the staccato and gymnastic styles that began to dominate dance after the 1960s.

Note also the remarkable lack of cuts. The dance is performed with only one cut, which means Astaire and Rogers had to get it perfect, the whole way through each of these two shots. It took 47 takes before they succeeded.

A pit in the dry-ice polar cap of Mars

A pit in the dry-ice cap of Mars
Click for full image.

This cool image is possibly of some of the most alien terrain on Mars. The photo to the right, rotated and cropped to post here, shows a pit (not a peak) in the dry-ice cap that covers a small portion of the southern polar ice cap on Mars. North is up. It was taken on June 16, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). In fact, at 88 degrees south latitude, the image is just about as far south as it is possible for MRO to take pictures. Beyond this the orbit does not reach.

If you look close, you can see that there are several distinct layers in the sunlight eastern interior slopes of the pit. The base of the pit itself appears to have ripples, as if their might be Martian dust trapped inside.

This is a very cold and alien place. The ground is made of dry ice. The temperatures are always cold, well below minus 100 degrees Fahrenheit.

If you look at the full image, you will see that, except for the very tiny pit nearby to the east, this pit is all by itself. If the underlying terrain caused this sinkhole to form, why only here?

The overview map below shows the location, which might help explain things.

There are no permanent political victories

12:43 pm

The fight for liberty never ends
The fight for liberty never ends

There has been much celebration in conservative circles today because of the victories in Florida yesterday in almost every school board election, sweeping leftists and Democrats from power.

Many of the winning candidates have been endorsed by the 1776 Project PAC, an organization that has been instrumental in flipping school boards from liberal to conservative across the country.

“We saw massive election victories all throughout the state of Florida tonight,” 1776 Project PAC founder Ryan Girdusky told Breitbart News Tuesday. “It shows the desire of parents and residents across the country for some normalcy in our education system, and that means pushing against transgender ideology, critical race theory, critical gender ideology, and equity which destroys merit in education.”

“The 1776 Project PAC hopes to take these successes across the country,” he said.

The sense I get, similar to the same sense I got when the Republicans finally regained control of the House of Representatives in 1994 — after decades of uninterrupted Democratic Party rule — is the false belief that yesterday’s victories at these school boards puts an end to bad and oppressive COVID policies and the teaching of the queer agenda and the racist and Marxist program dubbed critical race theory.

And as happened after 1994, the victories yesterday do no such thing. » Read more

Indian research project for China’s space station threatened by Chinese-India military conflict

11:21 am

A science instrument from India, slated to fly on a Chinese rocket to China’s Tiangong-3 space station, is now threatened by the military tensions between the two nations.

The project, called Spectrographic Investigation of Nebular Gas (SING), also involves collaboration with the [India] Institute of Astronomy [IIA], Russian Academy of Sciences, and has been designed and developed by research students at the IIA. The plan is to have it ready by the year end so that it can be launched in the summer of 2023. Though the plan is on schedule, scientists at the IIA are now consulting with the Indian Space Research Organisation (ISRO) as well as the Ministry of External Affairs (MEA) on whether they are in the clear to go ahead with the project.

Chinese and Indian troops have been engaged in a prolonged stand-off in eastern Ladakh. The two sides have so far held 16 rounds of Corps Commander-level talks to resolve the stand-off, which erupted on May 5, 2020, following a violent clash in the Pangong lake area.

It appears the Indian government is having second thoughts about this cooperative project. After decades of naive trust in the communists from both Russia and China, it seems India has finally realized the communists really have little interest in helping India, being more focused on using it for good PR while it steals Indian technology. Moreover, India now realizes that China has become a dangerous neighbor, willing to use its newfound power violently at the border between the two countries.
